I have a RPi3 with Ubuntu 15.10.3 installed. I shall bring that along tomorrow. I do not have a portable display, other than the touch screen that is attached to a RPi2. (I don't fancy changing the display ribbon cable more often than the minimum.) It would be nice to get hold of a portable HD display with HDMI.

Those who like to keep up-to-date with rpi-update might wish to know that the firmware update published on 30 April caused the sound on Ubuntu MATE 16.04 to be muted. I reverted back to the version published on 27 April and the sound worked again.

I am trying to run a Software Defined Radio app. http://gqrx.dk/ under Ubuntu MATE using a FUNCube dongle http://www.funcubedongle.com/?page_id=1073. The app. tends to consume most of the RPi 3's CPU resources which causes its temperature to rise. I have fitted a self-adhesive heat sink (from the Pi Hut) but it needs a stream of cooling air to keep the temperature from rising. If my 5v cooling fan arrives in time, I hope to bring the Pi along on Wednesday.
